The power module comprises

  • MOSFET based power switch to switch off the battery from all electronics
  • 5.38V DC/DC converter to supply the PixRacer autopilot, GPS, FrSky RC receiver
  • Battery voltage and current measurement circuit for the PixRacer
  • 5.38V DC/DC converter for the Raspberry Pis and the RFD868+ telemetry

The design is done with Easyeda and is available here: Easyeda SearchWingPower. The board has been produced at JLCPCB and two have been soldered at the ASSCON Demolab.

Voltera V-one

I have a Voltera V-One printer which can be used to dispense the solder paste. This needs to be tested. In the ASSCON lab we used the stencil printing method.

No talk. Just facts. Only the first board is without placement errors.
